How does installing this relay circuit board fix my RV air conditioner issues?

When the thermostat relay board fails, symptoms include fans that won’t stop, compressors that won’t engage or won’t turn off, and erratic heat-strip behavior. Replacing the damaged board restores the intended relay switching logic so each component receives correct signals from the thermostat.

• Resolves continuous fan operation by restoring proper relay sequencing
• Allows the compressor to engage and disengage according to thermostat settings
• Reinstates safe control of heat strip and furnace functions

What are the electrical and build-quality features of this folosem 3106996022 board?

This replacement board is manufactured with materials chosen for insulation, moisture resistance and flame retardance to reduce risk of short circuits and thermal failures. The green PCB contains the necessary relays, traces and connectors arranged to match common Dometic control housings.

• High-quality PCB substrate with corrosion-resistant soldering points
• Flame-retardant coating and enhanced insulation for safety
• Connector and mounting locations designed to align with OEM housings

Is installation straightforward and what should I check before replacing the board?

Installation is usually a direct swap if your unit uses the compatible board layout; basic electrical skills and wiring verification are required. Always disconnect power, document wiring positions, and verify model/part compatibility before fitting the new board to avoid damage.

• Power off RV shore or battery power before opening the unit
• Label or photograph connectors to ensure correct reconnection
• Confirm model and series compatibility against the listed part numbers
